coppercity Posted May 28, 2012 Report Share Posted May 28, 2012 A couple days ago during a training flight with a student we experienced a rough running engine while at lower power settings. We set the throttle to a position where the engine ran smoothly and returned for an uneventful landing. Looking at the indications on the EMS during the event the RIght side EGT would drop off significantly to 600-700 deg vs a 1000 on the left. My first thought was maybe a throttle cable had slipped. After opening the cowling though and inspecting the cables and throttle arms everything looked normal. Next place to look was the float bowls. I pulled the right side first since it seemed abnormal according to the EMS. Sure enough one of the floats was sunk to the bottom of the bowl! As long as the engine was at a higher power setting needing more fuel everything was fine, but as the fuel requirements went down with lower power settings and the float bowl overfilled then the engine ran rough. Replaced all the floats and everything runs like a champ again. Link to comment Share on other sites More sharing options...
